2000 hiv human functional genomics partnership program

Conditions: HIV Infections

Summary: background chronic hiv infection leads to a dysregulated immune system, even when full viral suppression is achieved. hiv causes persistent immune activation, relating to an array of common non-aids-related diseases such as cardiovascular disease (cvd) and non-alcoholic fatty liver disease (nafld). on the other hand, accelerated ageing of the immune system hinders effective immunity against infectious diseases and cancer. likewise, this derailed inflammatory balance creates a niche for persistent viral replication and reservoir, and prevents cure or functional cure. mechanisms behind this phenomenon are poorly understood. inclusion of a larger cohort of hiv-infected patients allows for a more precise assessment of the factors underlying the immune dysregulation. primary objectives * identify a set of candidate biomarkers that correlate with particular non-aids-related comorbidities * unravel biological processes associated with extreme hiv clinical phenotypes. * find therapeutic targets to identify novel assets or for repurposing of clinical phase assets from other disease areas for hiv. secondary objectives * evaluate potential relationship of host/immune profiles on efficacy, safety, and tolerability of standard care regimens. * evaluate the contribution of age, sex, and genetics in host-immune profiles that are: * distinct to hiv infection relative to controls in other cohorts; * associated with non-aids-related comorbidities in hiv infection relative to non-hiv chronic disease. study design 2000 hiv patients will be included in the cohort. the investigators estimate a 2-year inclusion and 2-year follow-up period and will strive for the inclusion of several clinical phenotypes and classical risk group patients. patients will be recruited from four dutch hiv treatment centers. at inclusion 1. collection of metadata using questionnaires and patient medical records 2. asses co-pathology (cvd and nafld) 3. blood will be drawn for genetic, epigenetic, proteomic, metabolomic, microbiome, immunological, and virological analyses after 2 years follow-up 1. collection of metadata using questionnaires and patient medical records 2. asses co-pathology (cvd and nafld) 3. blood samples will be collected for biomarker and infection/inflammation parameter analysis

study population a cohort with a total of 2000 hiv patients will be built, consisting of a discovery cohort (n=1200) and confirmation cohort (n=800). the investigators estimate a 2-year inclusion and 2-year follow-up period and will strive for the inclusion of several clinical phenotypes such as long-term non-progressors (\~2-3%), immunologic non-responders (\~3%), and rapid progressors (\~4-5%) and classical risk group patients such as men who have sex with men (msm), females, and subjects from sub-sahara africa. patients will be recruited from the following dutch hiv treatment centers: radboudumc (nijmegen), erasmus mc (rotterdam), olvg (amsterdam), elisabeth twee-steden ziekenhuis (tilburg). a sample size calculation cannot be provided due to the variable frequencies of the various traits in genome-microbiome interaction, and their effect on cytokine production. because of the explorative nature of this study, the size calculation will be variable depending on the type of polymorphism analyzed. the frequencies of the various microorganism classes in the colonizing microbiome is not known in our study population, and therefore power calculations are impossible to be performed. earlier studies in the human functional genomics project have assessed microbiome traits in 250-500 individuals. an earlier hfgp study included a uniform cohort of 200 hiv-infected individuals (all msm). the present study will also include hiv-infected patients with a more extreme phenotype, females and subjects originating from sub-sahara africa. because of this, the investigators decided to increase the number of individuals tested to 2000, consisting of a discovery cohort of 1200 subjects, and a confirmation cohort of 800 participants. study visits and procedures at inclusion 1. the investigators will collect metadata using questionnaires on lifestyle, health and clinical symptoms, including neuropsychiatric symptoms. relevant data will also be collected from the patients records in the medical centers and the hiv monitoring foundation. 2. co-pathology will be assesed: * cardiovascular risk scores (d:a:d risk score and framingham cvd score) will be collected as well as ecg and intima-media thickness (imt) measurements. * non-alcoholic fatty liver disease (nafld) assessment through liver ultrasound and fibroscan. 3. blood will be drawn (90 ml): * dna will be isolated for genetic and epigenetic analysis. * the function of the immune system will be analyzed at several levels using circulating white blood cells from venous blood. * metabolism and proteomics will be analyzed * virological analysis, characterizing the hiv reservoir, hiv resistance and viral sequences in circulating dna and rna. 4. microbiome analysis will be performed on stool and saliva samples. 5. urine sample will be collected for creatinine measurements and microbiome. after 2 years follow-up 1. the investigators will collect metadata using questionnaires on lifestyle, health and clinical symptoms, including neuropsychiatric symptoms. relevant data will also be collected from the patients records in the medical centers and the hiv monitoring foundation. 2. co-pathology will be assesed: * cardiovascular risk scores (d:a:d risk score and framingham cvd score) will be collected as well as ecg. * non-alcoholic fatty liver disease (nafld) assessment through liver ultrasound and fibroscan. 3. blood samples (10ml) will be collected for biomarker and infection/inflammation parameter analysis. patient informed consent procedure patients will always be approached first by a treating physician or specialized nurse. they will be provided with information and will be asked if a physician-researcher may contact the patient. if there is oral consent for this, the researcher contacts the patient in one week to ask if they are interested in participating in the study. the physician-researcher will answer any questions the patient may have and plan the first visit. the informed consent procedure will be conducted during the patient's first visit. patient registry procedures all patient data will be recorded only in coded form in a secure database with audit and edit trail (castor edc). during the informed consent procedure, the patient is given a study code. the identifying patient data and study code is kept in a password-protected key file, only accessible to the local research team. no patient-identifying data will leave the local medical center. in the questionnaires and ecrfs in castor, the investigators will enter as many data checks as possible biomaterials all biomaterial (blood, stool, urine, saliva) will be transported to and processed in the laboratory of experimental internal medicine of the radboudumc in nijmegen. here, all the biomaterial will also be stored collectively. all materials will be handled and stored only under the patient's study code. monitoring monitoring will be performed by an independent monitor according to the latest guidelines of the the netherlands federation of university medical centers. an initiation and close-out visit will be planned in plenary form with all the centers in radboudumc. there will be one extra visit per center. during these visits informed consents will be checked, as well as inclusion and exclusion criteria and source data verification in a small subset of total participants. data collection for patient registry baseline data collected from electronic patient files or the hiv monitoring foundation during inclusion
